SPECIFICATION formng part of Letters Patent No. 591,452, dated October 12, 1897.

Application filed April 15, 1897. Serial No. 632,255. (No model.)

To all whom, ili may concern:

Be it known that I, FRANK S. CHANCE, a citizen of the United States, residin'g at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Picture-Displaying Devices; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to wh-ich it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification. A

My invention relates to an improved device for consecutively displaying a series of pictures with sufficient rapidity to give to the figures in the pictures the appearance of moving.

The objects of my invention are to provide a device of that class that will be simple in operation, cheap of manufacture, and adapted to be made of such size as to permit of its being carried in thepocket.

A further obj ect is to provide an inexpensive means, in a device of the class described, for securing the sheets evenly upon the central roller or shaft, and in such a manner as to give the desired effect when they are rotated, a means for rotating said central shaft, and a means for causin g each succeeding picture to instantaneously take the place of the preceding picture and to allow each picture, as it appears, to stop long enough for the image to become fixed upon the retina of the eye.

With these objects in view my invention v consists in the construction and oombination of parts shown in the accompanying drawings, described in the following specification, and more particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of my device. Fig. 2 isa sectional view taken on the line y y of Fig. 3. Fig. 3 is a sectional view taken on the line :r a: of Fig. 2 5

and Fig. 4 is a fragmentary view illustrating the method of securing the sheets to the fabric, said fabric in turn secured upon the shaft.

1 is the case. 2 is the cranln 3 is the central shaft. 4 are the picture-sheets. 5 is the fabric upon which the sheets are secured, and 6 is a shoulder to 'engage, the outer edges of the sheets 4.

The case 1 may be made of any desired outline consistent with its purpose, and is provided with the Opening 14 in its upper edge, preferably V-shaped, as seen from the sides, through which the pictures are Viewed as they consecutively appear. The central shaft or roller 3 fits between the sides of the case 1 and has a central Opening 7 throughout its length, through which the aXle 8, which is a continuation of and integral with the crank 2, is adapted to pass. The shaft 3 may be of wood or, other suitable material and the fabrie 5 is rolled around said shaft and secured with glue or like a'dhesive substance. The sheets 4 to be attached to the fabric are spread out, with the ends of each succeeding sheet overlappin g the one beneath it, as shown in Fig. 4, thereby exposing theedge and a short section of the side of each sheet. Glue or other adhesive substance is then applied to the exposed portions 9 of thevsides and naturally fills up the slight de pression caused by the thickness of each succeeding sheet. This glue is indicated' by the black line 10 between the fabric 5 and sheets 4 in Fig. 4. The fabric 5, which has previously been cut to the proper Width and length, is then placed upon the glued surface of the sheets and pressed, so it will adhere firmly. The fabric is then wrapped around the shaft 3, as above described. This wrapping causes the outer edges of the sheets 4 to spread out, as in Fig. 2. The aXle 8 is j ournaled in the case l through openings 11. Said openings 11 are located V on a line between the center of the case l and the point of the shoulder 6, slightly above said center, as may be seen in Figs. 1, 2, and 3 of the drawings. It will be observed that this has the effect of causing the outer edges of the sheets 4 to come in contact with the inside edge of the case 2 at 12, and as the shaft 3 is rotated the sheets are curved back- Ward, by reason of said contact, until they come in contact with the shoulder 6, when the curve is increased, thereby causing the sheets to spring forward with great rapidity when they pass the shoulder 6, and as they strike the rear edge 13 of the V-shaped opening 14 there is a short pause in the movement, just sufficient to allow the image to IOO become fixed in the retina of the eye, when the next sheet Springs forward and tahes its place. This being repeated as the entire series of pictures or Views printed upon the Sheets 4 pass before the Opening in the case 1 give to the pictures the appearanee of move ment, as of Walking, dancing, &c.

It will be understood that the series of Views displayed in the case will be of the same Object or objeets in varied attitudes in order to give the above-deseribed e'lt'ects.

The device deseribed may be made very eheaply by forning the case 1 of pasteboard and printing the pictures upon the sheets 4: from printng-plates. The method of securing the sheets 4: upon the rol1er3 is inexpensive, yet places said sheets evenly in the position shown, which is essential to the proper working of the deviee. The axle S is fixed immovably in the Opening 7 in the shaft 3. Therefore the shaft is rotated as the erank 2, which is integral with the axle S, is turned. The instantaneous movement of the sheets carrying the pictures is eifected by the shoulder G and by having the axle B mounted out of the center, as shown. Each sheet as it passes the shoulder (3 Springs against the edge 13 so quickly that the eye cannot follow it, but its short stop or dwell as it strikes the edge 13 enables the eye to catch the image and retain it until the next view is presented. In operation it is only necessary to turn the erank 2 slowly and evenly, when the effects above deseribed will be attained.

I am aware that it is not new to present a series of Views consecutively in order to give the moving effect, but I am not aware that the effects described have ever been produeed by the means and in the Inanner employed in my device.

Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is*

1. As an article of manufacture, a picturedisplaying device having a case 1, provided with a V- shaped Opening in the top thereof, the roller 3, having a fabric 5, to which are adhesively attached sheets 4, removably fixed thereon, said roller journaled in said case 1 by means of the axle 8, said axle being positioned slightly ont of the center of said case for the purpose of bringing the outer edges of the sheets 4 into more decided contact with the shoulder G, projecting inwardly from the front edge of the V- shaped Opening in said case, substantially as set forth.

2. In a pieture-displaying deviee of the class deseribed, the conbination of the case 1,having the V-shaped top Opening 1 1 and the shoulder (5, pro j ectin g inwardly from the front edge of said V-shaped Opening with the roller 3, mounted upon the axle S, adapted to be rotated by the crank 2, said axlc S, journaled in the case 1, through openings 11, said openings located slightly above the center on a line with said shouldcr (3, and the sheets seeured to the fabrie 5, by means of adhesive substance, in the manner described, said fabric being in turn seeured 'upon the roller 3, as set forth.

3. In a picture-displaying device, the eonbination of the case 1, provided with the in wardly-projccting shonlder (5 seeured inside the case near the front edge of the Opening formed theren, and having the V-shaped Opening in the top thcreof, with a series of sheets i mounted upon a fabrie 5, and said fabric fixedly seeured upon a roller 3, said roller 3 mounted upon an axle S fixed in the case 1, upon a line between the center of said case and the point of the shoulder b', as shown and described.

i. The coinbination in a pieture-displaying device of the class deseribed, of the case 1, having the V- shaped Opening l-t in the upper part thereof, the inner depending shoulder G, and the axlc 8 nounted in said case 1, slightly above the center on a line with said p shoulder G, with the roller B'fixedly nounted upon the aXle S, and having the fabric 5 carrying the adhesively-mounted Sheets 4: lixcdly seeured thereon, as set forth.

In testimony whereof I allix my signature in presence of two witnesses.
